If you are unsure whether you need filler, anti-wrinkle treatment, or something else entirely, that uncertainty is well founded. Most facial concerns involve more than one contributing factor, volume, structure, movement, and skin quality often overlap. The only way to know what is actually driving your concern is a proper facial assessment with a qualified practitioner. This page helps you understand the different categories of facial change so you can arrive at a consultation with a clearer picture of what you are noticing. This guide was prepared by Corey Anderson, Registered Nurse (AHPRA NMW0001047575) at Core Aesthetics, a cosmetic injectables clinic in Oakleigh, Melbourne. Results vary between individuals; a consultation is required to assess suitability and develop a personalised treatment plan.
Why ‘I Don’t Know What I Need’ Is the Right Starting Point
The cosmetic injectable industry often implies that identifying your treatment is straightforward, that a sagging cheek means cheek filler, that forehead lines mean anti-wrinkle, that thin lips mean lip filler. In practice, it is rarely that simple.
Facial concerns almost always involve several overlapping processes happening at once. Volume can be lost in one area while structural changes occur in another. Muscle movement can create lines that look like they are caused by skin, when in fact the skin is entirely healthy. Structural features that have always been there can become more apparent as surrounding tissue changes over time.
When people arrive at a consultation having already decided exactly what treatment they need, they are sometimes right, but they are sometimes surprised to learn that what they noticed is driven by something different from what they assumed. That is not a failure of observation. It is a reflection of how genuinely complex facial anatomy is, and why a considered assessment matters before any treatment is decided.
The most honest thing a practitioner can do is work backwards from your concern, not forward from a treatment catalogue. That means understanding what is changing and why, before reaching for any tool.
If you arrive at a consultation saying “I’m not sure what I need, I just know something has changed”, that is a useful and accurate description. It gives the practitioner room to assess properly rather than simply confirm a decision already made.
The Four Things That Change in a Face Over Time
To understand whether filler is likely to be part of your picture, it helps to know the four main processes that alter facial appearance as we age. They are: volume change, structural change, skin change, and movement change. Most people experience some combination of all four, and the relative contribution of each varies between individuals considerably.
Volume Change
Facial fat is not evenly distributed and does not deplete evenly. There are discrete fat compartments, beneath the eyes, across the cheeks, around the mouth, along the jawline, in the temples, each of which has its own timeline and rate of change. When these compartments reduce in volume, the overlying skin loses its support and can begin to fold, shadow, or appear to sag.
Volume change is the primary area where dermal filler is used in assessment and treatment planning. When a practitioner is assessing whether a concern is volume related, they are looking at whether the tissues appear deflated, whether shadow patterns suggest structural support has reduced, and whether gentle lifting of the tissue reveals a structure that looks more like the person remembers.
Volume related changes tend to look like: hollowing beneath the eyes, deepening of the lines from the nose to the corners of the mouth, flattening of the cheek area, reduction in the fullness of the lips, loss of definition along the jawline, or a generally ‘flat’ appearance to the midface.
Structural Change
Bone is not static. The facial skeleton continues to remodel throughout adult life, the eye socket widens slightly, the midface shortens, the angle of the jaw changes. These skeletal changes are slow, incremental, and entirely normal, but they do alter the scaffolding that all the soft tissue sits on. Bone remodelling is one reason why changes that appear soft tissue in origin sometimes have a deeper architectural driver.
Structural changes are not addressable with injectable treatment alone, but understanding their contribution helps a practitioner identify which part of a concern is bone driven and which is soft tissue driven. This shapes where treatment may be placed if it is appropriate at all.
Skin Change
Skin texture, thickness, and elasticity all change over time. Fine lines at rest, changes in surface quality, and alterations in how the skin reflects light can make a face look different independent of any volume or structural shift. Skin related changes are generally outside the scope of injectable treatment, and a practitioner who is honest about this will say so clearly.
It is worth understanding this distinction before your consultation. Injectables can address volume and movement. They cannot address skin quality, texture, or the fine surface changes that fall within the scope of skincare, sunscreen, and dermatological treatments. If your primary concern is skin related, a cosmetic injectable practitioner should tell you that plainly.
Movement Change
Repeated muscle movement over decades creates lines in the skin that begin as dynamic (only visible during expression) and can become static (visible at rest). The forehead, the area between the brows, and the corners of the eyes are the most common areas. anti-wrinkle injections work by temporarily reducing the strength of specific muscle contractions. They do not add volume and they do not address skin quality directly, their mechanism is entirely different from filler.
If what you are noticing is most visible when you move your face, and less visible at rest, the concern is more likely movement related and anti-wrinkle assessment may be more relevant. If what you are noticing is present at rest, particularly as a hollow, shadow, or flat area, the concern is more likely volume related.
Many people have both, which is why separating them clearly requires a proper assessment.
When Is a Concern Volume-Related?
Volume related concerns are the most common reason people consider filler. Some indicators that volume may be a contributing factor to what you are noticing include:
- You can see a hollowing or shadow in an area that used to look full or smooth
- The skin in the area appears to have lost its lift or support, rather than having lines etched into it
- When you gently lift the skin in the area with your fingers, it looks more like how you remember it looking
- The change is gradual and has become more pronounced over several years
- The concern is most visible in certain lighting conditions, particularly side lighting that creates shadow
- The area is consistently visible regardless of your facial expression
None of these observations confirm that filler is appropriate, that requires assessment by a qualified practitioner, but they suggest that volume may be part of the picture worth exploring in a consultation.
Areas commonly assessed for volume related changes include: the tear trough (the groove beneath the eye and across the upper cheek), the midface and cheek region, the nasolabial fold area (from the nose to the corner of the mouth), the marionette area (from the corner of the mouth downward), the lips, the jawline, the temples, and the chin.
It is important to understand that volume loss in one area can create an apparent change in another. A loss of midface volume, for example, can cause the lower face to look heavier or the under eye area to look more hollowed, even if no change has occurred in those areas specifically. A practitioner assessing for volume will look at the whole face, not just the area of concern.
When Is a Concern Structural or Anatomical?
Some of what people notice in the mirror has always been part of their face. Structural features, the projection of the brow, the depth of the eye socket, the angle of the nose, the natural proportions of the lips, are anatomical rather than age related.
This distinction matters because treatment for structural features that have always been present is a different clinical decision from treatment for changes that have occurred over time. Neither is more or less valid, but the conversation is different, and the risks and expectations need to be framed differently.
One useful way to distinguish structural from age related concern is to look at photographs of yourself from ten or more years ago. If the feature you are concerned about is clearly visible in those photographs too, it is more likely structural. If the photographs show a different appearance, the change is more likely age related.
Structural features that people sometimes enquire about treating include: a lack of chin projection, an asymmetry in the face (most faces are naturally asymmetrical to some degree), a flat bridge of the nose, an undefined jawline that has always been present, or lips that have always been thin. These can be assessed in a consultation context, but the approach and expectations are different from treating an age related change.
A practitioner doing their job properly will make this distinction clear. They will also be honest if a structural feature is one that injectable treatment is not well suited to addressing, for example, if the asymmetry is bone level rather than soft tissue, or if the concern falls outside what injectable treatment can meaningfully change.
This is one reason why the consultation-based model matters. An honest practitioner will tell you what the treatment can and cannot achieve, rather than simply proceeding with a plan that addresses the symptom without discussing whether it fits the cause.
When Is a Concern Better Addressed by anti-wrinkle Than Filler?
anti-wrinkle injections work on movement. Filler works on volume. These are genuinely different tools with different mechanisms, and there are many concerns that one addresses and the other does not.
Concerns more likely to be movement related, and therefore more likely to be relevant to anti-wrinkle assessment, include:
- Lines that are most visible when you raise your eyebrows or make expressions, and less visible when your face is at rest
- The vertical frown lines between the brows that appear when you concentrate or squint
- Lines at the outer corners of the eyes that appear primarily with smiling or squinting
- A downward pull of the corners of the mouth caused by a specific muscle group
- A ‘bunny line’ across the top of the nose that appears when you scrunch your face
- Jaw muscle prominence related to teeth grinding or clenching
- Excessive sweating under the arms, on the palms, or on the scalp
Some concerns involve both volume and movement. The area around the mouth, for example, often involves some combination of volume loss in the lips and surrounding area, skin changes, and dynamic lines from years of expression. A practitioner assessing this area will consider both the volume and movement dimensions and discuss which, if any, they think is worth addressing.
The clearest way to distinguish: if the concern disappears entirely when your face is completely at rest, it is more likely movement driven. If the concern is present at rest and becomes a shadow or hollow, it is more likely volume driven.
When the Answer Might Be ‘Not Yet’ or ‘Neither’
One of the most useful things a consultation can reveal is that the timing is not right, or that injectable treatment is not the appropriate tool for a particular concern.
There are several reasons a practitioner might recommend waiting. The change you have noticed may be early and subtle, with no clear structural driver that treatment would address. The proportions of your face may be such that treatment in one area would alter a balance that currently works well. You may be approaching a consultation from a place of temporary distress, recent weight change, illness, stress, or a bad run of photographs, rather than a stable, considered position.
There are also concerns that injectable treatment is genuinely not suited to. Skin quality concerns, significant laxity, certain types of asymmetry, and features that fall within normal anatomical variation are among them. A practitioner who tells you clearly that treatment is not indicated, or that the risk benefit assessment does not favour proceeding, is giving you important, honest information. It is not a failure of the consultation. It is often the best possible outcome.
Core Aesthetics operates on a consultation-based model specifically because this kind of honest assessment is what protects patients from treatment that is not right for them. Saying no to a treatment when no clear need is identified is not a commercial decision, it is a clinical and ethical one.
If you arrive at a consultation uncertain about what you need, and you leave with a ‘wait and see’ or ‘nothing indicated today’ recommendation, that is a good outcome. It means the assessment was done properly and honestly, and you have a clearer picture of your face and what is happening to it over time.
What a Proper Facial Assessment Involves
A proper facial assessment before any injectable treatment is not a sales process. It is a clinical evaluation. At Core Aesthetics, this involves several elements that are worth understanding before you book.
History and context
The consultation begins with a conversation about what you are noticing, how long you have been aware of it, whether it represents a change from before or a feature you have always had, and what you would like to feel differently about. This context matters significantly. A practitioner who understands that you are primarily concerned about looking tired, rather than about a specific anatomical feature, will assess the face differently than one simply looking at a treatment request.
full face assessment
The assessment looks at the whole face, not just the area of expressed concern. This is because facial structures are interdependent. A change in the midface affects how the lower face looks. Volume loss beneath the eyes affects how prominent the nasolabial fold appears. Treating a single area in isolation without understanding the full picture can create imbalance that was not present before.
Structural and dynamic evaluation
The practitioner will assess the face both at rest and in movement. This identifies which concerns are movement related, which are volume related, and which are structural. In some cases, the cause of the concern becomes immediately apparent during this evaluation. In others, the picture is more complex and the practitioner may discuss this openly with you before making any recommendation.
Honest recommendation and alternatives
A good consultation ends with a clear explanation of what the practitioner found, what they think is driving the concern, whether any treatment is indicated, what that treatment would involve, what it would not address, and what the alternatives are, including doing nothing. There should be no pressure to proceed on the day of the consultation, and the recommendation should make clear what treatment can and cannot change.
Medical screening
A proper consultation also involves medical screening, a review of your health history, current medications, previous cosmetic treatments, allergies, and contraindications. This is not a formality. It is a required part of any responsible injectable assessment. The AHPRA guidelines introduced in September 2025 require that all nonsurgical cosmetic procedures be preceded by a consultation conducted by a registered health practitioner, with a cooling off period before any treatment proceeds.
Questions to Ask Yourself Before Your Consultation
Arriving at a consultation with some reflection already done makes the assessment more useful for both you and the practitioner. These are not diagnostic questions, they are not meant to replace the assessment. But they give you a clearer starting point for the conversation.
When did I first notice this? A change that has occurred gradually over several years is more likely age related. A change that appeared suddenly may have a different cause worth discussing.
Does it look different in photographs than in the mirror? Camera angle, lighting, and lens distortion can all make features appear differently. If the concern is only visible in certain photographs and not consistently in real life, this is worth noting.
Is it the same in all lighting? Volume related concerns often look more pronounced in harsh overhead or side lighting because they create shadow. Concerns that look the same in all lighting are often structural.
Does my face look different in the morning versus the evening? Some changes fluctuate with hydration, sleep position, and swelling from fluid retention. A concern that is significantly different at different times of day may have a contributing factor that is not structural at all.
Am I comparing myself to a specific age or photograph? It is useful to name what you are comparing yourself to. If you are comparing to yourself twenty years ago, the relevant conversation is about age related change. If you are comparing to an aesthetic ideal that may never have been present in your face, the practitioner can help put that in context.
What would feel like a good outcome? This does not need to be specific treatment. “I would like to look less tired” or “I would like to feel that my face looks more like itself again” are useful descriptions. “I want to look exactly like I did at 35” is a different kind of expectation that a good practitioner will want to discuss honestly.
The consultation-based Model and What It Means for You
Under AHPRA’s September 2025 guidelines for registered health practitioners performing nonsurgical cosmetic procedures, a consultation must be conducted before any treatment. There is a mandatory cooling off period, currently seven days for significant procedures, between the consultation and any proceeding treatment. This is a regulatory requirement, not a practice choice.
At Core Aesthetics, consultation-based has always been the model regardless of regulation. Corey Anderson, Registered Nurse, works with a low volume, one practitioner model specifically because proper assessment takes time and cannot be rushed to fit a high volume appointment schedule.
What this means practically for someone who arrives uncertain: the consultation itself is the value. You do not need to arrive knowing what you want. You do not need to arrive with a specific treatment in mind. What you need to bring is an honest description of what you are noticing, how it makes you feel, and what you would like to understand better.
The assessment will clarify what is actually happening, what (if any) treatment is appropriate, what it can and cannot change, and what the process would involve. If nothing is indicated, you will leave knowing that clearly, and that is a useful outcome. If treatment is indicated, you will leave with a specific, considered recommendation and time to think about it before deciding.
Uncertainty about what you need is not a barrier to a consultation. It is, in many ways, the most appropriate reason to book one.
For patients wondering whether the changes they are noticing relate to volume loss or structural ageing, the guide to facial balancing explains how proportional assessment works in clinical practice. Patients interested in understanding when filler may not be the right approach can read when filler is not the answer. Those who would like a broader picture of how treatment is planned over time may find the gradual aesthetic planning guide useful before booking a consultation.
Is this for you?
Consider booking a consultation if
- People who have noticed a change in their face but are unsure what is driving it
- People who want to understand whether any injectable treatment is appropriate for their concern before committing to anything
- People who have had a recommendation elsewhere that they want a second, careful opinion on
- People who are early in their thinking and want an honest picture of what their face is doing and why
This may not be for you if
- People under 18, cosmetic injectable assessment and treatment is not available
- People with an active skin infection, cold sore, or open wound in the area of concern
- People who are pregnant or breastfeeding
- People seeking same day treatment without a prior consultation and cooling off period
- People whose primary concern is skin quality, texture, or surface changes, these fall outside the scope of injectable assessment at Core Aesthetics
Suitability is confirmed at consultation. This list is general guidance, not a substitute for clinical assessment.
Frequently asked questions
How do I know if volume loss is causing the change I’m seeing?
Volume related changes typically appear as hollowing, shadow, or a loss of fullness in an area that used to look different, most commonly beneath the eyes, across the cheeks, around the mouth, or along the temples. If you notice that the concern is most visible in side lighting (which creates shadow in a hollow), or that gently pressing the area with your fingers makes it look closer to how you remember, volume may be a contributing factor. The only way to assess this definitively is through a consultation with a qualified practitioner who can evaluate the face structurally.
What if I’ve always had this feature, does that mean filler won’t help?
Not necessarily, but the assessment and conversation are different. Features that have always been present are structural rather than age related, and whether injectable treatment is appropriate depends on what the feature is, what change you are hoping for, and whether the risk benefit assessment is favourable. A practitioner should be honest about what treatment can and cannot achieve for a structural feature, and should not simply proceed because you have expressed a preference. Some structural concerns are well suited to assessment and possible treatment. Others are not, and an honest practitioner will tell you clearly.
Is it normal to not know what treatment I need before a consultation?
Yes, and it is actually a good starting position. Facial concerns are genuinely complex. Volume, structure, movement, and skin quality often contribute simultaneously, and the proportion of each varies between individuals. Arriving uncertain gives the practitioner room to assess properly rather than simply confirming a decision already made. At Core Aesthetics, the consultation is structured to work from your concern backwards to the cause, not forward from a treatment list.
What happens if I’m assessed and the recommendation is to wait?
A ‘wait and see’ recommendation is a good outcome. It means the assessment was done properly and nothing was found that would justify the risk of treatment at this time. You leave with a clear understanding of what is happening with your face, why treatment is not indicated now, and (if relevant) what to watch for over time. There is no obligation to book any treatment following a consultation, and a practitioner who recommends waiting is doing their job correctly.
What is the difference between a volume concern and a movement concern?
Volume concerns are present at rest and typically appear as hollowing, shadow, or loss of fullness, they do not change significantly with facial expression. Movement concerns are driven by muscle activity and are most visible during expression, frown lines, forehead lines, and crow’s feet are the most common. Many people have both. anti-wrinkle injections address movement related concerns. Dermal filler addresses volume related concerns. During assessment, the practitioner distinguishes between movement related and volume related concerns and recommends accordingly.
Can filler address concerns around the eyes?
The under eye area (tear trough) is one of the more commonly assessed areas for filler, as volume loss in this region can create hollowing and shadow that makes a face appear tired. However, the eye area is also one of the most technically demanding to assess, under eye concerns can be driven by volume loss, structural factors, skin quality, or fluid retention, and the appropriate response differs significantly depending on the cause. A dedicated suitability assessment is always required for the under eye area before any treatment is considered.
How long does a proper facial assessment take?
A thorough consultation, including a full medical history, facial assessment at rest and in movement, discussion of your concerns and expectations, and a clear recommendation with time for your questions, typically takes 30 to 45 minutes. Assessments that take significantly less time than this are unlikely to be comprehensive. Under the AHPRA September 2025 guidelines, a consultation must precede any nonsurgical cosmetic procedure, and there is a mandatory cooling off period before treatment proceeds.
What if my concern is something filler cannot address?
A practitioner doing their job properly will tell you clearly if filler is not the right tool for your concern. Skin quality, skin laxity, significant asymmetry driven by bone structure, and features outside the scope of injectable treatment are all situations where honest communication means telling you that no, or limited, treatment is indicated. Core Aesthetics operates as an injectable only clinic. If your concern falls outside that scope, you will be told plainly, with an explanation of why and (where possible) a direction toward a more appropriate assessment.
